I would request an MRI. I know you are probably going to get a few other suggestions for other diagnostics... but the MRI was the one that really showed my breast cancer in it's full glory. I was also given a clean bill of health after 15 mammograms (YES... 15) and an ultrasound. My breast was also very dense and they couldn't really get a clear shot.
7 months later i felt a lump in my breast that turned out to be invasive ductal cancer a 2.2 cm tumor staged 2B with one positive node.
I want to commend you for pursuing this further. My breast also felt funny and I had odd sensations but I just went along with what the doctor said.... "It was ok." When your gut is whispering something to you.... listen. Please follow through with your suspicions.
Take care, and please keep us posted. Sharon
